Seperti yang sudah ditunjukkan oleh banyak orang, biasanya ada transaksi yang tahan lama, sebagian besar karena saya ketinggalan menggunakan SET TRANSAKSI IMPLICIT ON, yang seharusnya tidak digunakan sama sekali. Untuk mengetahui alasannya, periksa artikel berwawasan Brent Ozar
Bagaimanapun, Anda bisa mendapatkan daftar transaksi tertunda yang bertahan lama menggunakan kueri berikut.
SELECT

[s_es].[login_name] AS [Login Name],
